RECORDING DEVICE.

Application filed March 7, 1928. Serial No. 259,853.

The present invention relates to recording devices, and aims to providea novel device of simple and inexpensive construction to be secured tothe instrument board of an automobile to indicate, in association withthe mileage register, when the motor oil should be changed and the cargreased or lubricated.

With the foregoing and other objects in view, which will be apparent asthe description proceeds, the invention resides in the construction andarrangement of parts, as hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimed,without depart ing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure1 is a front view of the recording device, and

Fig. 2 is a rear perspective view thereof.

The device comprises a back 7 of wood or other suitable material, infront of which are placed the sheets 8 and 9 of paper, metal or othersuitable material, which are spaced apart to accommodate the disks 10and 11 of paper, sheet metal or other suitable material, each of whichhas on the face thereof the numerals O to 9, inclusive, to be exposedthrough the respective openings 13 in the front sheet 9. There are twosets of disks, each including the side disks 10 and the intermediatedisk 11. The side disks project slightly from the sides of the bodycomposed of the back 7 and sheets 8 and 9, while the disks 11 pro trudeslightly from the ends of said body, in order that the disks may beconveniently turned by the fingers. The sheet 9 has print- 7 ed orotherwise provided thereon the false openings 14 with naughts therein tocomplete the five numeral spaces, and the units and tens are ignored sothat only the first three numerals require changing. Pins 12 extendthrough the sheets 8 and 9 and disks 10 and 11 into the back 7, to mountthe disks for rotation, and'the disks may be readily turned, whenchanging motor oil and greasing the car, in order to indicate at whatmileage of the machine the next change of oil and greasing should bemade.

The sheet metal frame 15 is disposed in front of the margins of thesheets 8 and '9, to

- hold the edges and ends of the sheets in place,

and has spaced portions 16 at its ends bent across the ends of thesheet-s and back and behind said back. The frame 15 also has tongues orstraps 17 at its side edges near the.

corners bent across the edges of the sheets and back and behind theportions 16. The

frame 15 has portions 18 bent rearwardly across the edges of the sheetsand back between the ends thereof, and said portions 18 have outstandingears 19 in order to fasten the device to the instrument board or othersurface by means of screws, nails or other securing elements. Theportions 16 are spaced apart to accommodate the disks 11, and theportions 18 are located between the disks 10, so that the rearwardlybent portions of the frame 15 are located between the disks and will notinterfere therewith. i

A piece '20 of celluloid, glass, or other suitable transparent materialis preferably disposed across the sheet 9 behind the frame 15, toprotect the sheet 9 and openings 18.

The device is convenient in use, being readily set by hand, without.requiring operating mechanism or pencil notations. VVit-h the exceptionof the'pins 12 the entire device is composed of sheet material, and maybe manufac tured at small cost.

Having thus described the invention, what is claimed'as new is I 1. Adevice of the character described comprising a sheet having openingstherein, a back behind said sheet, disks mounted for rotation betweensaid sheet and back and having numerals to be exposed through saidopenings, said disks projecting beyond said sheet and back, and a framein front of said sheet having portions extending across the edges of.said sheet and back and engaging behind said back.

2. A device of the character described coinprising a sheet havingopenings'therein, a back behind said sheet, disks mounted for rotationbetween said sheet and back and having numerals to be exposed throughsaid openings, and a. frame bearing against the marginal portion of saidsheet and having portions extending rearwardly and engaging behind saidback andportions adapted for attachment to an in'st-rument'board orother support, said disks projecting from said sheet and back betweensaid portions.

3. A device of the character described comprising a sheet havingopenings therein, a

back behind said sheet, disks mounted for rosecuring elements to fastenthe device to an tation between said sheet and back and havinstrumentboard or other support, said disks ing numerals to be exposed throughsaid projecting from said sheet and back between openings, and a framein front of the marsaid portions.
